My personal reason was I'm afraid that it could go lower than the current price and as you can see, there are lots of those project that hasn't been recovered after it dumped to the bottom. This is one of the reasons why I quickly sold all the tokens I got from bounty before. Those participants who think the same way are more clever because they are dumping the cion the day they received their rewards, as for me I sold them about one to two weeks after the distribution just hoping for some positive changes in its price.
